%X This study aimed to investigate the characteristics of the coupling of
the center of pressure (COP) movement and toes in older adults during
one-legged standing (OLS). Participants were community dwelling older and
younger <span>adults. Toe vertical force during
the OLS was recorded using a plantar-press</span>ure distribution system, and
the vertical forces in the hallux, little toe, and the <span>first and fifth metatarsophalangeal (MP) joints were analyzed. A
cross-correlatio</span>n function was performed to examine the coordination
between toes and between COP movement and four regions of the foot. The cross-correlation
functions showed no significant difference in coefficients between toes. The
OLS duration in the older adults was significantly correlated with the
coefficient between the medial-lateral component of the COP and the first MP
region.</span><span> </span><span style=\"font-family:&quot;\">This study suggests that
it is important to press the first MP region appropriately relative to COP
movement to maintain the OLS.
